Is there deduplication on the replication flow?

[gandalfwise]

Hi
About replication, I know that the VM files on the destination storage are not deduplicate because it's sored on the native format.
But is there DEDUPLICATION + COMPRESSION on the replication flow or only COMPRESSION?
Thanks for your help.

Hi Arnaud,

Yes, during replication our source proxy consolidates the content of virtual disks by filtering out overlapping blocks, zero-data blocks and blocks of swap files, so only those data blocks that have actually changed since the previous job run will be sent.

Thanks!

Will Veeam De-Dupe between similar VMs for the replication stream?

For example if I have two Windows Server 2008 R2 VMs, will veeam perform de-duplication between the same OS files for the replication transfer?

No. Also, please note that we are doing backups and replication on block level, not on file level.

Ok, what about backup streams?

If I perform a backup of two windows server will Veeam dedupe before sending the backup over the WAN?
If so then could I run Backup jobs for the dedupe benefit and then use those backups to seed replication?

I am trying to move some VMs from on premise to a datacenter and curious about the fastest way to achieve this with Veeam.

It's the same.

If bandwidth is your major concern, then the optimal way would be to backup VMs locally, then move/transfer the deduped and compressed backup files to a datacenter and use them for replica seeding.
